Sometimes you need a little extra encouragement to hit the trail. The latest update to Pumatrac for iOS should give you that friend-based push to lace up when you’re feeling particularly lazy. Social competitions make up most of what’s new in version 2.0, bringing in the same functionality between the iOS and Android app. To start a challenge, simply set a distance, a duration and invite your buddies. From there, group leaderborads allow for motivation (read: trash talk) and checking in on your temporary frenemies’ progress. Each time you clown your pals, you’ll earn a rank. After checking the leaderboard, make sure you download the app on all your Android devices.
